Description
UNTTED STATES PATENT RICHARD EMANS, OF'MANSFIELD, NEW JERSEY.
MODE 0F CONSTRUCTING CLAMPS USED BY SHOEMAKEBS, HARNESS-MAKERS, AND OTHERS FOR HOLDING LEATHER.
Specification of Letters Patent No. 420, dated October 6, 18S-7.
To all whom t may concern l Be it known that I, RICHARD EMANS, of Mansfield, in the county of Warren and State of New Jersey, have invented an 1mprovement in the manner of constructing clamps used by shoemakers, harness-makers,
and others in sewing and' stitching leather;
and I do hereby declare that the following is a full and eXact description thereof.
In the accompanying drawing the clamp is represented as used by shoemakers without a bench or stool, but to be held between the knees; its sides or cheeks are hinged, or otherwise connected together in the usual manner; the object in view being to retain these clamps, with the leather between their jaws, by means of the appendages t0| be described, without the necessity of embracing it forcibly between the knees, orholding it by any other muscular pressure.
Figure l shows the clamp in perspective; Fig. 2, a section thereof down the middle.
A, A', is a compound joint by which the jaws may be held in any required position; the joint being attached to them by pins a, a; it will loe seen from the drawing that by opening and closing the jaws, the notched part ZJ, of the bow A', will work in and out through a inortise in the hinged jaw, prepared for that purpose. Within this jaw there is a sliding plate c, o, which may be raised by the thumb piece d, so as to relieve it from the notches of the part Z), of the curved joint piece; the thumb piece is forced out by a spiral or other spring; the drawing showing the whole action of this and other parts.
Instead o-f the compound joint A, A. a piece of iron, having suitable notches on it,
may -be Xed to one aw, and pass throughV a mortise in the other, a sliding piece catching into the notches. The clamp may also be used on a bench or stool, like those employed by harness makers, '&c., and will be found much more convenient than those which are acted upon by a screw, o-r by a treadle.
I claim as my invention- The modes herein described of closing, holding, and liberating, the clamps used by shoemakers and others, by having a notched piece of metal, or joint piece, fastened to one jaw, and sliding through the other, with a sliding catch and a thumb piece, operating substantially in the way above shown.
RICHARD EMANS. Witnesses:
